But again you face the technicality: is providing access to already-existing documents "testimony" in the sense the fifth amendment intends? You can't torture someone into producing documents that don't exist, obviously! Nor is going to jail for obstruction of justice "coercion", effectively by definition.

I'm not saying I disagree with you in principle, I'm saying that very reasonable courts might not. This isn't a cut and dry argument, at all.
